Hmm. I'm guessing it's from Jonathan Belson, an ex-Essex University person who played a lot of text adventures, but I haven't heard from him in 3 years. It could equally well be from someone I've never heard of, or from some other Jonathan B. I do know but who's getting blocked from recall by the name I came up with first.
The text of the message seems, in its form, eerily like that of my A Post-Modernist Essay, too.
Well, Jonathan B., whoever you are, if you wanted to bug me to distraction, you succeeded!
